Specification of Letters Patent.

Patented Mar.. it., 191W.

Application filed December 14, 1908. Serial No. 467,325.

To alt whom 'it may concern: l

Be it known that I, LEWIS J." CARNEY, a citizen of the United States,residing at Boston, county of Suffolk, Commonwealth oflilassacliusetts,have invented certain new and useful Improvements inVentilators, of which the following is a specification. j

rlhis invention relates to ventilators vand particularly to windowventilators. In devices of this sort it is of great importance that theventilator be readily applied to windows of varying width without thenecessity of exact measurements or close fitting requiring cutting orsawing on the spot. It is also desirable that such devices bepositionable in the window so as to be held therein in such a way thatno draft shall be permitted through cracks and so firmly adjusted to thewindow as to relieve the ventilator from the risk of being crushed ordisabled by the descending sash.

To the end, therefore, of producing a ventilator which shall have theseseveral advantages and possibilities I have devised my presentventilator in which I have included various features of structuraladvantage and improvement. All this will be more fully set forth anddescribed in the specification which follows in which I have described acertain ventilatoras illustrative of my invention and have shown thesame in the drawings as an embodiment thereof.

rllhroughout the drawings and the description like reference numeralsare employed to indicate corresponding parts and in the drawings Figure1 is a view showing ,the direct draft closed, Fig. 2 is a view showingthe indirect draft closed and the direct draft opened, Fig. 3 is a frontview of a portionofv a window from without with the ventilator applied,and Fig. 4 is a side sectional view on the line 4-4, Fig. 1.

1 isthe outside wall, 2 the top, 3 the inside wall, and 4 the bottom ofa ventilator box which is closed by ends 5. In the outside Wall 1 areair ports 6 grouped near the middle of the ventilator box and in the top2 are nine ports 7 spaced along the entire distance. The upper edges ofthe sides 1 and 3 are extended and grooved at 11 and 31 to form a slideWay in which Work three slides 8 each pierced by a pair of 'ports 9.

to make it possible to open the three central ports 7 or close thesethree and open either or both of the sets of 3 ports at each end, or

to-open all of the ports 7 at once. In this way it is possible to openthe middle groups giving a direct. draft or to close the middle groupand open one or both end groups to secure an indirect draft'or to openall to secure a full draft.`

At eachend of the ventilator box I pro- V vide a wing 10 of about vthewidth of ,thev

box but attached to it so. as to depend Y- slightly below its loweredge; The wing is vertically slotted at 11 and is adjustably fastened.by a bolt and thumbnut to the box through a horizontal slot -12 whichper'- mits its adjustment in two directions. In`

order to adjust the ventilator to a window, therefore, the thumbnuts at13 are slackened and the wings pushed down until the ventilator boxrests in the inside window sill and the bottom of the wings rest on theouter sill or ledge. This affords a firm seat for the ventilator b oxand a suitable rest vlfor the wings 10 so that there is no danger of thebox becoming displaced and crushed by a descending sash or of the wings1() beingy v1. In a window ventilator a Ventilating l box having airpassages therethrough and vertically adjustable lateral Wings'forreceiving the sash. i

2. In a window. ventilator a Ventilating `box adapted to rest on aWindow sill within the line of the sash and having air passagestherethrough, a pro vertically adjustable on the outer face o said boxand adapted to be positioned with its lower edge against the outer sillin line with the sash to receive said sash and support it upon its upperedge.

3. In a window ventilator a Ventilating l box having air passagestherethrough and lateral wings vertically and horizontally adjustablethereon.

These ports are so arranged in the slides as j 4. In a ,windowventilator a Ventilating box and means adjustable relative thereto forsupporting a sash when said box is in contact With a window sill.

5. In a window support a Ventilating box, an intake port in its outsidewall centrally ot the ends thereof, ports in the top of said boxarranged centrally and at each end thereof and means for closing saidports independent l G yIn a window ventilator a Ventilatingr box havingintake ports centrally arranged in its outer wall, a plurality of escapeports disposed throughout the length of another wall of the box andmeans for closing the ports adjacent to said intake ports.

7. Inra device of the class described, a

Ventilating sill-box adapted to be disposed inside of the line of thesash and a wing adjustably mounted on the outer face of said ventilatorfor Vertical or horizontal movement thereon and adapted to have itsupper edge disposed below the top of said vent-ilator.

8. In a device of the class described, a Ventilating sill-box adapted tobe disposed inside of the line of the sash and a Wing adjustably mountedon the outside face of said ventilator for vertical or horizontalmovement thereon and adapted to have its upper edge disposed below thetop of said ventilator and its lower edge adapted to englage the -sillbelow the bottom of the sas i.

9. In a window ventilator a ventilator box and means for supporting thesash, said means being independent of said box and vertically adjustablethereto.

10. In a window ventilator, an inside sillbox and an outside flangepiece vertically adjustable on said box to fit the thickness of thewindow sill.

11. A device of the class described, comprising a ventilator box andmeans for securing a draft, directly or indirectly therethrough.

In testimony whereof, I affix my signature in presence of two Witnesses.
